** Description changed: Hello, I am experiencing a 100% reproducible kernel regression (on my machine) - that causes an instant system reboot when launching a specific Flatpak - application. The system was previously experiencing random kernel - panics, which were thought to have been resolved by purging a - conflicting system-wide ROCm installation. + that causes a near-instant kernel panic, which leads to a system reboot + when launching a specific Flatpak application. The system was previously + experiencing random kernel panics, which were thought to have been + resolved by purging a conflicting system-wide ROCm installation. What I expected to happen: The Flatpak application 'Supercell WX' should launch normally. What happened instead: - The moment the application is launched, the system instantly reboots - without displaying a visual kernel panic message on screen. No "Kernel - Panic" or "BUG" messages are written to the journalctl logs from the - crashed boot; the log simply cuts off. + The moment the application is launched, the system locks up and then + displays a visual kernel panic message on screen.
